I am going to use MDF as my screen foundation as the small size will easily allow for this to be done with one sheet. The projector will be 9 feet from the screen. Projector being used is an Optoma HD20. Light will be completely controlled in the room.

What paint formula should I use with this application? It cannot be sprayed on, must be rolled or brushed.

Thanks for the help!

MDF will require priming on both sides to seal it properly to prevent bowing / warping, and to equalize absorption.

Both sides should receive 2 coats - 1 coat of Primer at a time. The "rear" needs not receive any sanding after any coat, but the "Screen" side should get a light sanding after the 2nd Primer Coat.

When your ready to roll on a Finish coating, consider RS-MaxxMudd LL for an advanced solution, or a very light Neutral Gray for something crazy simple. Check out the DIY Sticky " http://www.avsforum.com/t/929997/beginners-guide-to-simple-diy-painted-screens " and read up on rolling as well as choosing a basic N8.5 Gray

You should expect to roll at least 3 light Finish coats of whatever you choose.

Make sure you also prime all 4 edges.
